IMPROVEMENT IN ORE-SEPARTORS.

Specification forming part of Letters Patent N 0. 204,083, dated May 21, 1878 5 application filed January 8, 1878.

To all whom it may concern:

Be it known that I, PAscHAL PLANT, of the ment in Apparatus for Separating Gold from,V

Quartz or other earthy matter, of which the following is a clear and exact description, reff erence being had to the accompanying drawings, making part of this specification, in Whih- Figure 1 is a perspective view, and Fig. 2 is a plan, with the cylinders and journal-boxes in section.

In the drawings, A are posts. B are metallic strips fastened to the posts A, having ears 011 the bottom to be fastened on the oor. C are longitudinal cross-pieces, and D are vertical cross-pieces to make the frame stationary. 0n the top vertical cross-pieces D are journalboxes d and d', in which the shaftlgearing and driving-pulley revolve. E E are extra vertical cross-pieces, on which guides F F are supported. An axle, G, with a large gearwheel, H, and a driving-pulley, I, revolves in journal-boxes d' d, to set the apparatus in motion, by a gear-wheel, J, which is fastened to a horizontal inclined crank-shaft, K. .This shaft K revolves the cylinder L L in a rotary and inclined motion, which produces a forward and rotary motion to the quartz or other matter. Thesecylinders are provided in the interior with ribs or rings l, and on the outer ends with collars Z', fastened or cast to it. Z" are boxes on the inner ends to receive the ore from hoppers l, which are fastened to the frame by standards 1. On the same end of the cylinders there are trunnions f f cast or fastened to them, which move -to and fro in the guides F F.

The object of my invention is to separate gold from quartz or other earthy matter, dryindependent of water.

The rotation of the cylinders causes the separation of the heaviest substances from the lightest by .centrifugal force. The heaviest is retained within the cylinder by the ribs or rings, while the lightest'loats over the ribs or rings and out the end of the cylinder.

In the drawing l have shown the cylinders set and operated horizontally; but it is obvious that for .some purposes it may be neces'- sary to arrange the cylinders vertically or at any degree of inclination between a vertical and horizontal line.

' The frame may be made with three upright posts connected -together on the top, and the cylinders may be made perpendicular or coni-v cal, and may be guided by hinges or connecting-rods instead of trunnions. f

The cylinders also may be fixed on wagon or other conveniences for easy transportation.

' The ribs or rings may be made inclined or curved. Waterandmercurymay be used. A ir may also be used by means of fans xed on the' shaft, inside or otherwise.

I claimv 1. The bent shaft K, in combination with the cylinder L, substantially as shown and described, and whereby a conical motion is.

imparted to the cylinder, for the purpose set forth.v

2. The bent shaft K, with the cylinder loosely attached thereto, incombination withthe guides F and pins f, substantially as described.

3. The bent shaft K, with the cylinders L loosely attached, in combination with the guides F, guide-pinsf, and gear-wheel H and pinion I, as described, and for the purpose set forth. v
